The sapphire temporary wafer carrier is a high-performance substrate engineered for advanced semiconductor packaging processes, particularly for ultra-thin wafer handling and heterogeneous integration applications.<\/p>\n

It is widely applied in 2.5D\/3D IC packaging, TSV, RDL processes, fan-out wafer\/panel level packaging (FOWLP\/FOPLP), and temporary bonding\/debonding workflows.<\/p>\n

Designed with ultra-high rigidity and excellent thermal stability, the carrier provides a precise and stable mechanical platform for wafer thinning and backside processing, enabling reliable handling of wafers below 50 \u03bcm thickness while maintaining dimensional integrity under complex thermal cycling conditions.<\/p>\n
